On Wednesday, May 5, a blue whale was sighted just 13 nautical miles east of Truro by the Center for Coastal Studies Right Whale Aerial Surveillance team.
Blue whales (Balaenoptera musculus) are the largest animal ever known to have lived, growing up to 100 ft in length and weighing between 76 – 150 tons. The Northwest Atlantic blue whale population is estimated to be between 400- 600 individuals and they are mostly commonly documented in the Gulf of St. Lawrence in Canada.
There are sporadic sightings of them off New England, but when they are seen they are generally in very deep water hundreds of miles offshore. The most recent confirmed sighting of blue whales in the area was by the New England Aquarium aerial team in February, where they documented two individuals 130 miles offshore.
